ABSTRACT:
A discrimination apparatus for deriving pattern recognition information by selecting predetermined components of a video image for generating a narrow-width identification signal. This is achieved by removing the higher frequency components of the video image of the object to be identified and generating a frequency information signal and an amplitude information signal of the unknown pattern. These information signals are then compared with known amplitude and frequency information signals of known patterns stored in a data base. An identification is made when the respective signal match within predetermined tolerances and associated information is output in response to this identification.
